Very soon.

I could (and have) thrown together a cheaper system, but this is what I want. Hopefully others agree.
It is based on
Raspberry Pi 4 / Linux.
10" touch screen. Second HDMI output for a big screen if you have the space and an extra HDMI monitor or TV laying around.
Everything is al la carte so you just get what you need to start, expand at any time. Everything is interconnected with ethernet (not on your network, just local.) Any length cable you care to run between devices. Future software upgrades include multiple grow space monitoring and control. Up to 127 total devices will be the max.
Uses I2C for remote communication. Sensors, relays, etc are just plugged into the bus and the software sees it and adds the functionality. I'll show you in video later this week.
EDIT: I'll add some more tech specs here now that my belly is full and the Cards are swinging the bat. We're up 1 nothin and are crushing it in National Central. Any baseball growers out there?
So, what you got there is the main "box" - I dunno Prototype 1X47Ftq sounds good. The part with the screen. That device houses the Pi, the Capacitive Touch Screen, Touch Screen Driver, HDMI Driver, Power Suppl... ah who cares, you quit reading.
Prototype 1X47Ftq runs Linux. On a circuit board that is a complete PC in a single board. Friggin excellent.
Prototype 1X47Ftq has a main circuit board that has GPIO pins - not something a normal PC has. They let you interface directly with hardware like relays, PH sensors, Male plant detectors (j/k. Not that, but other cool stuff.)
There is a bus hub prototype displayed. It is nothing more than a place to plug in 6 things, really 5 things and a line back to mama. Mama being Prototype 1X47Ftq.
Haha, if you are still reading this you are stoned.
Those 5 things might be Temp, RH, CO2, O2, Humidity... did you notice I said RH 2 ways there? No? Stoner. You know who you are.
Future upgrades I'm looking at are things like a plug in spectrometer - I might just rent that out, maybe a PPFD meter? I have a camera hooked up now, that's interesting.
Another upgrade that I have working here for mine is a programmable iR blaster that you train it how to flash to control a device (I'm using it to control my mini split AC and my dehumidifier). Just more things that plug into the bus, wherever it's closest to pick it up. Just daisy chain off any device and plug it in.
I'm working on lighting control, but that's a lower priority because my lights have an app that is acceptable to drive them directly.
Another obvious plug in to the bus is AC control. I have 2 AC remotes I'm using (very Alpha stage, wires hanging kinda staus) that's what's next to complete. Then we will have control over any ac device that is based off a timer, a calculation, an internet lookup (moon cycles - fuck - I don't know you figure it out) or simply when sensor A does this you turn that thing on. It's just an inkbird via software at it's simplest.
The other box is the wet probe connection. Again, just another thing on the bus. This one is user configurable to add sensors at any time. Don't want Dissolved Oxygen today? Get it later. If you can twist a Phillips head, you can add any sensor you like. Well, within reason, not like spider mite fart detectors. Cumon man.
OK this is way too long already, but I gotta tell you about the OS / software.
Still up 1-0.
